The invention relates to a method for preparing alumina in the form of beads having a sulfur content of between 0.001% and 1% by weight, and a sodium content of between 0.001% and 1% by weight, with respect to the total mass of said beads, said beads being prepared by formation through dewatering of a highly dispersible alumina gel. The alumina gel is in turn prepared according to a preparation method employing specific precipitation, enabling at least 40% by weight of alumina to be obtained with respect to the total quantity of alumina formed at the end of the gel preparation method, from the first precipitation step, the quantity of alumina formed at the end of the first precipitation step being able to attain 100%. The invention further relates to the use of alumina beads as a catalyst support in a catalytic reforming process. |
